I witnessed 3 Coyotes playing near an open space park in Boulder, CO. Each time I would try to approach to get a shot, the group would run away. I made a plan to anticipate their movements, and setup in the grass about 100 meters away. After waiting about 15 minutes, the one male Coyote wandered into the open area scanning the surroundings. This was the best shot of about 7 before the Coyote noticed my presence and ran off again. Shot with a Canon 1D Mark II and a 500mm f/4L IS lens and a 1.4x teleconverter.
